Effect of oral premedication on the anaesthetic efficacy of inferior alveolar nerve block in patients with irreversible pulpitis - A systematic review and network meta-analysis of randomized controlled trials.
This systematic review (SR; PROSPERO database: CRD42017075160) and network meta-analysis (NMA) identified the most effective oral premedication for anaesthetic success of inferior alveolar nerve blocks (IANB) in cases of irreversible pulpitis. Medline and Ebscohost databases were searched up until 10/2017. Randomized controlled trials (RCT) studying the effect of oral premedication, alone or in combination, on the success of IANB for cases of irreversible pulpitis, compared to placebo or other oral premedications, were included. Quality of the included studies was appraised by the revised Cochrane risk of bias tool for randomized trials. Pairwise analysis, NMA and quality of evidence assessment using GRADE criteria were performed. Nineteen studies (n = 1654 participants) were included. NMA demonstrated that compared to placebo, dexamethasone was most effective in increasing anaesthetic success (RR, 2.92 [95% CI 1.74,4.91]; SUCRA = 0.96), followed by NSAIDs (RR, 1.92 [95% CI 1.63,2.27], SUCRA = 0.738) and Tramadol (RR, 2.03 [95% CI 1.18,3.49], SUCRA = 0.737). Premedication with acetaminophen added to NSAIDs demonstrated similar efficacy as NSAIDs alone (RR, 1.06 [95% CI 0.79,1.43]). Sensitivity analyses proved the superiority of dexamethasone or NSAIDs over any other premedications. Subgroup analyses of specific dosages in comparison with placebo demonstrated that dexamethasone 0.5 mg was most effective, followed by ketorolac 10 mg, piroxicam 20 mg, ibuprofen 400 mg + acetaminophen 500 mg and Tramadol 50 mg. Ibuprofen 400 mg, 600 mg and 800 mg had a significantly improved IANB success, while Ibuprofen 300 mg had no effect. Oral premedication with dexamethasone, NSAIDs or Tramadol significantly increased anaesthetic success. More trials are needed to evaluate the premedication effects of dexamethasone or Tramadol for improved anaesthetic success of IANB when treating irreversible pulpitis.

Efficacy and Safety of Pulpal Anesthesia Strategies during Endodontic Treatment of Permanent Mandibular Molars with Symptomatic Irreversible Pulpitis: A Systematic Review and Network Meta-analysis.
INTRODUCTION
Several strategies have been investigated for achieving successful pulpal anesthesia during endodontic treatment of mandibular molars with symptomatic irreversible pulpitis. However, comprehensive evaluation and identification of the most efficacious and safe intervention are lacking. We aimed to determine this using network meta-analysis.
METHODS
MEDLINE, Embase, Cochrane Central, CINAHL, and Scopus databases were searched. Study selection and data extraction were performed in duplicate. Eligible randomized controlled trials were meta-analyzed to estimate the treatment effects (odd ratios [ORs]; 95% credible interval (CrI) and surface under the cumulative ranking curve (SUCRA)]. CINeMA software (University of Bern, Bern, Switzerland) was used to assess the quality of results.
RESULTS
Thirty-seven interventions from 46 studies were identified. Compared with the common practice of an inferior alveolar nerve block with 2% lidocaine, a supplemental intraosseous injection was ranked the most efficacious with very low to moderate confidence (2% lidocaine + preoperative nonsteroidal anti-inflammatory drugs [NSAIDs] + acetaminophen [OR = 74; 95% CrI, 15-470; SUCRA = 97%], 2% lidocaine + preoperative NSAIDs [OR = 46; 95% CrI, 8-420; SUCRA = 94%], 2% lidocaine [OR = 33; 95% CrI, 14-80; SUCRA = 93%], 2% lidocaine + preoperative opioids + acetaminophen [OR = 20; 95% CrI, 4.4-98; SUCRA = 86%], and 4% articaine [OR = 20; 95% CrI, 6.3-96; SUCRA = 87%]) followed by supplemental buccal and lingual infiltrations using 4% articaine + preoperative NSAIDs (OR = 18; 95% CrI, 6-56; SUCRA = 86%; very low confidence). No major safety concerns were reported.
CONCLUSIONS
Very low- to moderate-quality evidence suggests intraosseous injection using 2% lidocaine with 1:100,000 epinephrine or 4% articaine with 1:100,000 epinephrine or buccal and lingual infiltrations of 4% articaine with 1:100,000 epinephrine are superior strategies to achieve pulpal anesthesia during endodontic treatment of mandibular molars with symptomatic irreversible pulpitis. Preoperative NSAIDs or opioids with or without acetaminophen may increase the efficacy of these injections.

BACKGROUND
Irreversible pulpitis, which is characterised by acute and intense pain, is one of the most frequent reasons that patients attend for emergency dental care. Apart from removal of the tooth, the customary way of relieving the pain of irreversible pulpitis is by drilling into the tooth, removing the inflamed pulp (nerve) and cleaning the root canal. However, a significant number of dentists continue to prescribe antibiotics to stop the pain of irreversible pulpitis.This review updates the previous version published in 2016.
OBJECTIVES
To assess the effects of systemic antibiotics for irreversible pulpitis.
SEARCH METHODS
We searched Cochrane Oral Health's Trials Register (to 18 February 2019); the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 1) in the Cochrane Library (searched 18 February 2019); MEDLINE Ovid (1946 to 18 February 2019); Embase Ovid (1980 to 18 February 2019); US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (searched 18 February 2019); and the World Health Organization International Clinical Trials Registry Platform (searched 18 February 2019). There were no language restrictions in the searches of the electronic databases.
SELECTION CRITERIA
Randomised controlled trials which compared pain relief with systemic antibiotics and analgesics, against placebo and analgesics in the acute preoperative phase of irreversible pulpitis.
DATA COLLECTION AND ANALYSIS
Three review authors screened studies and extracted data independently. We assessed the certainty of the evidence of included studies using GRADE. Pooling of data was not possible and a descriptive summary is presented.
MAIN RESULTS
No additional trials could be included in this update. One trial at low risk of bias evaluating oral penicillin in combination with analgesics versus placebo with analgesics, involving 40 participants was included in a former update of the review. The certainty of the evidence was rated low for the different outcomes. Our primary outcome was patient-reported pain (intensity/duration) and pain relief. There was a close parallel distribution of the pain ratings in both the intervention (median 6.0, interquartile range (IQR) 10.5), and for placebo (median 6.0, IQR 9.5) over the seven-day study period. There was insufficient evidence to claim or refute a benefit for penicillin for pain intensity. There was no significant difference in the mean total number of ibuprofen tablets over the study period: 9.20 (standard deviation (SD) 6.02) in the penicillin group versus 9.60 (SD 6.34) in the placebo group; mean difference -0.40 (95% confidence interval (CI) -4.23 to 3.43; P = 0.84). This applied equally for the mean total number of Tylenol tablets: 6.90 (SD 6.87) used in the penicillin group versus 4.45 (SD 4.82) in the placebo group; mean difference 2.45 (95% CI -1.23 to 6.13; P = 0.19). Our secondary outcome on reporting of adverse events was not addressed in this study.
AUTHORS' CONCLUSIONS
This Cochrane Review which was based on one low-powered small sample trial assessed as at low risk of bias, illustrates that there is insufficient evidence to determine whether antibiotics reduce pain or not compared to not having antibiotics. The results of this review confirm the necessity for further larger sample and methodologically sound trials that can provide additional evidence as to whether antibiotics, prescribed in the preoperative phase, can affect treatment outcomes for irreversible pulpitis.

Meta-Analysis Review
Anaesthetic efficacy of incorporating different additives into lidocaine for the inferior alveolar nerve block: A systematic review with meta-analysis and trial sequential analysis.
BACKGROUND
Incorporating an additive into lidocaine is a method to enhance the efficacy of the inferior alveolar nerve block (IANB) in mandibular posterior teeth.
OBJECTIVES
To assess the efficacy of incorporating additives into lidocaine in the success rate of IANB for teeth with the diagnosis of normal pulp (NP) or symptomatic irreversible pulpitis (SIP).
METHODS
Randomized controlled trials (RCTs) assessing the incorporation of additives into lidocaine on the pulpal anaesthesia success rate of mandibular posterior teeth were searched in PubMed, Scopus, Web of Science, Ovid, EBSCO, Embase, and Cochrane databases up to 1 December 2021. The risk of bias (RoB) was assessed by the Cochrane Risk of Bias Tool. A random-effects model was employed to calculate the pooled risk ratio (RR) with a 95% confidence interval (CI), using STATA 16. The trial sequential analysis (TSA) was applied to calculate the required information size (RIS). The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach was used to assess the certainty of the evidence.
RESULTS
Of 6966 records retrieved initially, 14 trials (8 for NP and 6 for SIP groups) were included in qualitative and quantitative syntheses. All trials were categorized as low and unclear RoB for NP and SIP groups, respectively. In the NP group, with 307 participants, no significant effect was observed for additives incorporated into lidocaine (RR: 0.84; 95% CI: 0.53-1.32; I = 98%). Subgroup analysis revealed that adding mannitol led to a higher success rate (RR = 1.24; 95% CI: 1.15-1.34; I = 7.16%). In the SIP group, with 434 participants, no significant effect was shown when the additives were incorporated (RR = 1.22; 95% CI: 0.98-1.52; I = 0%). Likewise, in subgroup analysis, incorporating mannitol or sodium bicarbonate demonstrated no significant effect (RR = 1.76; 95% CI: 0.93-3.32; I = 18.41% and RR = 1.06; 95% CI: 0.65-1.72; I = 53.5%, respectively).
DISCUSSION
TSA revealed that the outcome was "inconclusive" for each group. The certainty of the evidence was graded as "very low" and "low" for NP and SIP groups, respectively.
CONCLUSIONS
The very low to low certainty of evidence indicated that incorporating additives into lidocaine did not increase the efficacy of IANB and supplemental injections are still necessary to help practitioners achieve painless dentistry.

Meta-Analysis
The purpose of this systematic review and meta-analysis was to evaluate utilisation of supplementary techniques for pain control during root canal treatment of lower molars with irreversible pulpitis. The literature was searched using electronic databases up to year 2012. Seventeen studies with 1504 participants were included and each study compared experimental interventions with a standard treatment, i.e. the inferior alveolar nerve block. Changing the injection techniques or supplemental injection had no significant effect on pulp anaesthesia compared to the standard treatment (P = 1.00 or P = 0.14), whereas changing anaesthetic features and increasing anaesthetic volumes resulted in significantly higher rates of anaesthesia than those of the standard treatment (P = 0.03 and P = 0.007, respectively). Premedication with non-steroidal anti-inflammatory drugs (NSAIDs) also significantly increased the success rate of anaesthesia (P = 0.001). Taken together, increased anaesthetic volumes and premedication with NSAIDs provide predictable anaesthesia and more pain control during endodontic treatment of lower molars with irreversible pulpitis.

Review
BACKGROUND
The exposed pulp has been the topic of numerous studies, but well-designed and well-executed comparative trials on the outcome and treatment of these teeth have been limited.
OBJECTIVES
This study was conducted to answer the following questions: in patients with nontraumatic pulpitis associated with no or nonspontaneous pain in permanent teeth, (i) is direct pulp capping or pulpotomy (partial/full) as effective as selective or stepwise caries removal [Population/participants, Intervention(s), Comparator(s)/control, Outcome(s) (PICO) 1], (ii) is pulpotomy (partial/full) as effective as direct pulp capping (PICO 2) and (iii) is pulpotomy (partial/full) as effective as a pulpectomy (PICO 3), in terms of a combination of patient and clinical reported outcomes, with 'tooth survival' as the most critical outcome?
METHODS
A literature search was conducted using Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Central Register of Controlled Trials from inception to November 3rd 2021. Grey literature and contents of the major subject journals were examined. Eligibility criteria followed the PICO questions. Two independent reviewers performed study selection, data extraction and appraisal; disagreements were resolved by a third reviewer. The risk of bias was assessed by the revised Cochrane risk-of-bias tool for randomized trials.
RESULTS
Three randomized clinical trials (RCTs) were included in the review. No study fulfilled the criteria to answer PICO 1. There were no significant differences in the reported outcomes between investigated treatments in all included RCTs. None of the included studies reported the most critical outcome 'tooth survival'. A high loss of patients during the follow-up period was observed.
DISCUSSION
Although a few studies fulfilled strict eligible criteria, the results of this systematic review clearly highlight a paucity of available evidence. At the present time, clinical decisions cannot be substantiated by direct comparative trials.
CONCLUSIONS
Based on limited evidence, this systematic review discovered no significant differences in effectiveness between compared vital pulp treatments in managing nontraumatic pulpitis associated with no or nonspontaneous pain. Further high-quality RCTs are necessary to investigate the effectiveness of direct pulp capping or pulpotomy (partial/full) compared to selective or stepwise caries removal.

Review
PURPOSE
Endodontic disease is one of the most common causes of bacterial odontogenic sinusitis (ODS). Diagnosing ODS of endodontic origin involves otolaryngologists confirming sinusitis, and dental specialists confirming endodontic sources. The purpose of this study was to conduct a multidisciplinary literature review to highlight clinical and microbiological features of ODS, and the most optimal diagnostic modalities to confirm endodontic disease.
METHODS
An extensive review of both medical and dental literature was performed by rhinologists, endodontists, and an infectious disease specialist. Frequencies of various clinical and microbiological features from ODS studies were collected, and averages were calculated. Different endodontic testing and imaging modalities were also evaluated on their abilities to confirm endodontic disease.
RESULTS
ODS patients most often present with unilateral sinonasal symptoms for over 3 months, purulence on nasal endoscopy, and overt dental pathology on computed tomography (CT). Subjective foul smell, and maxillary sinus cultures demonstrating anaerobes and α-streptococci (viridans group) may be more specific to ODS. For endodontic evaluations, cold pulp testing and cone-beam CT imaging are most optimal for confirming pulpal and periapical disease.
CONCLUSION
Diagnosing ODS requires collaboration between otolaryngologists and dental specialists. Clinicians should suspect ODS when patients present with unilateral sinonasal symptoms, especially foul smell. Patients will generally have purulent drainage on nasal endoscopy, and both sinus opacification and overt dental pathology on CT. However, some patients will have subtle or absent dental pathology on CT. For suspected endodontic disease, endodontists should be consulted for at least cold pulp testing, and ideally cone-beam CT.

Meta-Analysis
INTRODUCTION
The purpose of this study was to evaluate the efficacy and safety of postoperative medications in decreasing pain after nonsurgical endodontic treatment using a network meta-analytic approach.
METHODS
MEDLINE, Embase, CENTRAL, CINAHL, and Scopus were searched (until July 31, 2019). Two reviewers selected eligible randomized controlled trials and extracted and meta-analyzed data to estimate the treatment effects of pain assessed on a 0-100 scale (mean difference [MD]); 95% credible interval [CrI], and surface under the cumulative ranking curve [SUCRA]) at 6-8, 12, 24, and 48 hours postoperatively after the administration of various interventions. The Cochrane risk of bias tool was applied to eligible trials. The overall quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach obtained from the CINeMA Web application (University of Bern, Bern, Switzerland).
RESULTS
Eight interventions among 11 studies were identified: nonsteroidal anti-inflammatory drugs (NSAIDs), NSAIDs + acetaminophen, NSAIDs + benzodiazepines, NSAIDs + opioids, corticosteroids, opioids, acetaminophen, and placebo. Compared with placebo, nonsurgical endodontic treatment pain 6-8 hours postoperatively improved with NSAIDs + acetaminophen (MD = -22; 95% CrI, -38 to -7.2; SUCRA = 73%; moderate confidence) and NSAIDs (MD = -21; 95% CrI, -34 to -7.6; SUCRA = 68%; very low confidence). At 12 and 24 hours, only NSAIDs were effective in decreasing postoperative pain. At 48 hours, no treatment resulted in significant pain reduction. Corticosteroids and opioids did not significantly decrease pain. No major safety concerns were reported.
CONCLUSIONS
Very low- to moderate-quality evidence suggests that NSAIDs or NSAIDs + acetaminophen administered after nonsurgical endodontic treatment lead to a clinically relevant decrease in postoperative pain for patients with irreversible pulpitis or pulpal necrosis and are the most effective treatments available. Postoperative corticosteroids or opioids did not significantly decrease postoperative pain.

Meta-Analysis Review
INTRODUCTION
The effectiveness of intracanal cryotherapy for reducing postoperative pain is unclear. The objective of this systematic review was to evaluate the effect of intracanal cryotherapy on postoperative pain after root canal therapy in patients with pulpal or periradicular pathosis.
METHODS
We searched PubMed, Embase, Scopus, and the Cochrane Library as well as the top 3 endodontic journals for relevant articles. We included randomized controlled trials that included adults. Our main outcome was postoperative pain intensity measured with a validated scale. We assessed the risk of bias using the Cochrane criteria and the quality of the included studies using Grading of Recommendation Assessment, Development, and Evaluation. We used a random-effects model for meta-analysis.
RESULTS
Eight studies involving 810 patients were included. The overall risk of bias was moderate. Seven of 8 studies used a visual analog scale to measure pain intensity. Compared with controls, intracanal cryotherapy significantly reduced postoperative pain at 6 (mean difference = -1.37; 95% confidence interval [CI], -0.61 to -2.14; P < .05; I = 76%; moderate-quality evidence) and 24 hours after the procedure (mean difference = -1.43; 95% confidence interval, -0.70 to -2.15; P < .05; I = 89%; moderate-quality evidence). There was no significant effect on pain at 48 and 72 hours and 7 days after the procedure.
CONCLUSIONS
Moderate-quality evidence suggests that intracanal cryotherapy (ie, using cold saline irrigation as a final irrigant) significantly reduces the intensity of pain at 6 and 24 hours after root canal therapy. Future clinical trials assessing the effectiveness of intracanal cryotherapy are advocated.

Meta-Analysis
INTRODUCTION
The current systematic review and meta-analysis aimed to evaluate the success rate of partial pulpotomy in treating permanent posterior teeth with carious vital pulp exposure. A secondary aim was to assess the prognostic factors using a meta-regression.
METHODS
An electronic search was performed for studies from January 1950 to November 2018 in the following databases: PubMed, ScienceDirect, and Cochrane. All searches were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Clinical studies evaluating the success rate of cariously exposed vital human permanent posterior teeth treated with a partial pulpotomy were selected. Only randomized clinical trials and prospective clinical studies were included for evaluation. The Newcastle-Ottawa Scale and the Cochrane Collaboration's tool were used to evaluate risk assessment.
RESULTS
From the 218 studies identified through the initial search, 11 studies qualified for the final analysis (5 randomized clinical trials and 6 prospective studies). The results of the meta-analysis indicate a success rate of 98% (confidence interval [CI]: 0.94-1), 96% (CI: 0.92-0.99), and 92% (CI: 0.83-0.97) after 6 months and 1 and 2 years of follow-up. Examining the probable prognostic factors using meta-regression analysis, only preoperative pulp status (P = .001) was identified as a significant factor, with studies including teeth with the presumptive diagnosis of irreversible pulpitis displaying significantly lower results. The final solution, pulp capping material, apex closure, and the age of the patient did not affect the treatment success rate (P > .05).
CONCLUSIONS
The available data suggest that a partial pulpotomy results in high success rates in treating cariously exposed permanent posterior teeth up to 2 years. Six months of monitoring can be considered an appropriate period when evaluating the success of a partial pulpotomy although more clinical and radiographic controls are essential to ensuring success.
